A website is selling sets of golf clubs for $63, but mentions that they originally cost $105. What percentage is the discount?
Subtract to find the amount of discount then divide by original price
105 - 63 = 42
42/105 = 0.40 = 40%
Answer: 40%
Find two consecutive odd integers whose sum is 122
Answer:
if the numbers were the same, they'd both be 61
So, try 60 and 62.
Algebraically, if x is the smaller number,
x + x+2 = 122
2x = 120
x = 60

What is the multiplicative rate of change of the function? One-third Two-thirds 2 9.
The multiplicative rate of change of the function will be [tex]\frac{2}{3}[/tex].
What is the multiplicative rate?It is an arithmetical operation that calculates the product of two values, first described in terms of repeated addition.
When the value of x is changed from 1 to 2, the value of y is changed from 6 to 4.
The multiplicative rate of change of the function will be
[tex]\frac{4}{6} = \frac{2}{3}[/tex]
When the value of x is changed from 2 to 3, the value of y is changed from 4 to [tex]\frac{8}{3}[/tex].
The multiplicative rate of change
[tex]\frac{\frac{8}{4} }{4} = \frac{2}{3}[/tex]
When the value of x is changed from 3 to 4, the value of y is changed from [tex]\frac{8}{13}[/tex] to [tex]\frac{16}{9}[/tex].
Hence the multiplicative rate of change of the function will be [tex]\frac{2}{3}[/tex].

IF NR = 8 ft, what is the length of arc NMP. Round to the nearest tenth.
Check the picture below.
since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.
[tex]\textit{arc's length}\\\\ s=\cfrac{r\pi \theta }{180}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=8\\ \theta =198 \end{cases}\implies s=\cfrac{(8)\pi (198)}{180}\implies s\approx 27.6[/tex]

Kathleen jarred 12 liters of jam after 4 days. How much jam did Kathleen jar if she spent 6 days making jam? Assume the relationship is directly proportional.
Given parameters:
Number of liters of jam = 12 liters
Number of days = 4 days
Unknown:
Number of jams jarred in 6 days = ?
Solution:
Let us first find the rate of Kathleen in this jarring work;
Rate = [tex]\frac{Number of jams}{Number of days}[/tex]
Rate = [tex]\frac{12}{4}[/tex] = 3liters/day
Now, the number of jams in 6days;
Number of jams = Rate x number of days
Number of jams = 3 x 6 = 18jams
The number of jams jarred in 6 days is 18

Which modified box plot represents the data set? 39, 39, 3, 40, 46, 48, 60, 62, 62.
Answer:
To find this question, you first should put your data values in order from least to greatest. Doing so would look like this:
39, 39, 3 , 40 , 46 , 48 , 60 , 62 ,62
Now find the median, the middle number. This would be 46. This would also be the middle point on your box and whisker plot. Looking at your answer choices, the only one that has the middle point at 46 is the last one. So that is your answer.

At the baseball game last weekend, the Smith, Jones, and Garcia families each bought snacks from the concession stand. The Smith family purchased 3 hot dogs, 1 drinks, and 4 pretzels for $19.50. The Jones family spent $10.00 on 2 hot dogs, 2 drinks, and a pretzel. The Garcia family bought 3 hot dogs, 2 drinks, and 2 pretzels for $15.
What is the cost of a drink?
Answer:
The cost of a drink is $1.5
Step-by-step explanation:
Let x be the cost of 1 hot dog , y be the cost of 1 drink and z be the cost of 1 pretzel
We are given that The Smith family purchased 3 hot dogs, 1 drinks, and 4 pretzels for $19.50.
So, 3x+y+4z=19.50 ---1
We are also given that The Garcia family bought 3 hot dogs, 2 drinks, and 2 pretzels for $15.
So, 3x+2y+2z=15 ---2
We are also given that The Jones family spent $10.00 on 2 hot dogs, 2 drinks, and a pretzel.
2x+2y+z=10 ---3
Substitute the value of y from 1 in 2 and 3
3x+2(19.50-3x-4z)+2z=15 and 2x+2(19.50-3x-4z)+z=10
-3x-6z+24=0----4 and -4x-7z+29=0 ---- 5
Substitute the value z from 4 in 5
[tex]-4x-7(\frac{-24+3x}{-6})+29=0[/tex]
x=2
Substitute the value of x in 4
-3(2)-6z+24=0
z=3
Substitute the value of x and z in 1
3(2)+y+4(3)=19.50
y=1.5
Hence the cost of a drink is $1.5

Which of these is a simplified form of the equation 7z 2 = 8 2z 1z? 10z = 6 10z = 10 4z = 6 4z = 10.
Like terms are those terms that are having the same variables and order. The simplified form of the given equation 7z+2=8+2z+1z is 4z=6.
What are Like terms?Like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
The given equation to us is 7z+2=8+2z+1z, simplifying the equation we will get,
[tex]7z + 2 = 8 + 2z + 1z\\\\\text{Bring the like terms on the same side of the equation}\\\\7z -2z-1z = 8 -2\\\\7z-3z=6\\\\4z = 6[/tex]
Hence, the simplified form of the given equation 7z+2=8+2z+1z is 4z=6.
